Six STEM Tweets
Six tweets that celebrate engineering and all things STEM.
I scroll so you don’t have to.
We had some amazing cloud formations in North Texas today.
A big thanks to member FF for sending some photos and a Wikipedia link describing the clouds.
Clouds! Big fluffy clouds!
I described the clouds as marshmallow-y and fluffy but I guess the folks who named them had a slightly different viewpoint.
These clouds are called Mammatus clouds (Wikipedia link)
A big thanks to FF for the udder-ly fascinating bit of information.

China just landed a probe on the far side of the Moon - this time nearer the south pole, to gather volcanic samples using a scoop and drill, and blast them back to Earth. They've partnered with Sweden, France and Italy. Proving the tech needed to land Chinese astronauts by 2030.

Landing a probe on the moon is a challenge. Getting materials back is even more challenging. Scientists and engineers around the world will be watching as this mission unfolds.

Math is all around us!

Bats and dolphins evolved echolocation in the same way (down to the molecular level).
An analysis revealed that 200 genes had independently changed in the same way and this is an extreme example of convergent evolution.

Evolution continues to reveal fascinating details.

To give context on age, Grace Hopper began computing at 38, completed the first compiler at 46, helped shape COBOL at 53, kept developing COBOL for the Navy in her 70s, retired from the Navy at 80 & then became a consultant for the Digital Equipment Corporation.

We at #SixSTEMTweets are big fans of Grace Hopper. She was a pioneer in many computing areas.

Here's the proof: x³-1=(x-1)(x²+x+1) and this number is composite unless x-1=1 ⇒ x=2 and x³=8

The world's heaviest and widest double-decked vertical-lift bridge
Lifts from 4 ft to 100 ft of clearance for boats to go underneath— dailySTEM (Chris Woods) (@dailystem)

I love Chris and his interest and passion for STEM.
I had no idea about this engineering marvel of a bridge - the Houghton Hancock Bridge in Michigan, USA
According to it’s Wikipedia page at https://en.wikipedia.org/wiki/Portage_Lake_Lift_Bridge
This moveable bridge is a lift bridge with the middle section capable of being lifted from its low point of four feet clearance over the water to a clearance of 100 feet (30 m) to allow boats to pass underneath. The bridge is the world's heaviest and widest double-decked vertical-lift bridge. More than 35,000 tons of concrete and 7,000 tons of steel went into the bridge, which replaced the narrow 54-year-old swing bridge, declared a menace to navigation on the busy Keweenaw Waterway.
Hancock and Houghton hold an annual celebration called Bridgefest to commemorate the opening of the bridge which united their two communities.
It goes from 4 ft to 100 ft! And they have an annual celebration for the bridge!
How cool!
That’s it for this issue.
